High levels of activity aid arterial functioning; might help women more than men

31.05.2012
Indiana University researchers found that the highly active middle-aged subjects in their study appear to avoid the arterial stiffening -- when arteries become less compliant as blood pumps through the body -- that typically comes with aging.

A reduction in compliance of the body's large arteries has been shown to occur with age and with inactivity. It also is considered a risk factor, predictive of future cardiovascular disease, such as high blood pressure and stroke. The study compared the arterial compliance of highly active swimmers with that of people who reported being only moderately active or completely inactive.

The difference between the highly active participants and the others was significant, said Maleah Holland, a graduate student in the Counsilman Center at IU Bloomington, but there was little difference in compliance in the highly active group regardless of age or sex.

"This reinforces the idea that activity could be more influential than aging on some health factors," said Joel Stager, professor and director of the Counsilman Center in the School of Health, Physical Education and Recreation's Department of Kinesiology.

While there was little difference in arterial compliance between men and women in the highly active group, Holland found a significant difference between men and women in the inactive or moderately active group, with men faring better than the women.

"Oddly, women, particularly the inactive women, show the greatest risk for cardiovascular disease as compared with other groups," Holland wrote in her research report. "Thus, conversely, habitually high levels of physical activity may pose a greater benefit for women than for men." This may have been because the inactive women were more sedentary than the men classified as inactive.

The study involved 21 men and 28 women. The 33 highly active subjects were U.S. Master Swimmers who reported more than 200 minutes of vigorous activity a week. For comparison purposes, jogging would be considered a moderate level of activity, while interval training, which combines shorter but more intense periods of running with rest, would be considered vigorous activity.

Holland will discuss her poster presentation at 8 a.m. Thursday, May 31. Co-authors are Stager, David A. Tanner, Colleen M. McCracken and Hao Guo, Department of Kinesiology in the School of HPER, and Peter R. Finn, Department of Psychological and Brain Sciences in the College of Arts and Sciences at IU Bloomington.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
